SOP: Groundwater <br />from Monitoring Wells <br />Standard Operating Procedure: <br />Groundwater Sampling from Monitoring Wells <br />Scope and Application <br />This Standard Operating Procedure (SOP) describes the procedures to be used to collect groundwater samples <br />using traditional purging and sampling techniques. Monitoring wells must be developed after installation and <br />prior to groundwater sample collection. During precipitation events, groundwater sampling will be discontinued <br />until precipitation ceases or a cover over the sampling area and monitoring well has been erected. <br />Both filtered and unfiltered groundwater samples may be collected using this SOP. Filtered samples may be <br />obtained using a 1.0-, 0.45-, or 0.1-micron disposable filter. <br />II. Personnel Qualifications <br />Field sampling personnel will have current Mine health and safety training. In addition, field sampling personnel <br />will be versed in the relevant SOPS and possess the skills and experience necessary to successfully complete the <br />desired field work. <br />Personnel conducting groundwater sample collection activities should have previous groundwater sampling <br />experience or a degree in envirotunental sciences, engineering, hydrogeology, or geology. <br />III. Equipment List <br />The following materials shall be available, as required, during groundwater sampling <br />• site plan of monitoring well locations and site Field Sampling Plan (FSP); <br />• appropriate health and safety equipment, as specified in the Mine Health and Safety Plan (HASP); <br />• monitoring well construction logs or tables and historical water level information, if available; <br />• decontaminated pumps, tubing, and other equipment necessary for purging; <br />• generator or battery for operation of pumps, if required; <br />• pump, if required, in accordance with the FSP or Work Plan (parameter-specific [e.g., submersible, bladder, <br />peristaltic]); <br />• polypropylene rope; <br />• buckets to measure purge water; <br />• water-level well probe; <br />• water-quality meter; <br />• appropriate analytical method water sample containers with preservative, as needed (parameter-specific); <br />• filter, as needed, in accordance with the analytical method and parameter; <br />• appropriate blanks (trip blank supplied by the laboratory), as specified in the FSP; <br />• Ziploc-type freezer bags; <br />• appropriate transport containers (coolers) with ice and appropriate labeling, packing, and shipping materials; <br />• appropriate groundwater sampling log (example attached); <br />• chain-of-custody forms; <br />11/6/06 <br />SOPO6Grountlwatar Sampling~.line.tloc <br />
